Testing Material Tolerance to Avoid Deformation or Damage

Jewelry drop tests are a crucial quality control step in evaluating a jewelry product's ability to withstand impact from accidental drops during actual use, transportation, and storage. Their core function is to identify design, manufacturing, or material flaws in advance, ensuring product safety, durability, and consumer rights. Specifically, the core functions are as follows:

Core Function: Ensuring Product "Risk Resistance" and Avoiding Failures in Real Scenarios

During circulation and use, "accidental drops" are high-frequency risk scenarios for jewelry (such as dropping while wearing, collisions due to damaged packaging during transportation, or slipping off display counters). The core purpose of drop tests is to simulate these scenarios and verify whether the product can withstand the impact without functional or safety issues. This includes:

Verifying Structural Stability to Prevent Component Detachment

Jewelry often consists of multiple component assemblies (such as prong or bezel settings for gemstones, clasps for pendants, clasps for bracelets, and earring posts). The impact from a drop can cause structural loosening.

Testing Material Tolerance to Avoid Deformation or Damage

Different jewelry materials (metals like K gold, silver, and platinum, and gemstones like diamonds, jade, and pearls) have significant differences in physical properties (hardness, toughness, and brittleness). Drop tests can verify whether the materials are suitable for the product design:

Whether brittle materials (such as jade, rubies, and sapphires) will crack or develop fissures due to impact;

Whether soft metals (such as pure silver and 18K gold) will deform due to impact (such as rings becoming misshapen or bracelets losing their arc);

Whether special materials (such as pearls and amber) will show surface scratches or flaking due to impact (pearl layers are fragile and prone to wear from drops).

Ensuring Wearing Safety to Prevent Consumer Injury

If jewelry drops and subsequently presents "hidden risks" (such as sharp edges from broken links or loose gemstones that could scratch the skin), it directly threatens consumer safety. Testing can identify such hazards in advance:

Whether metal parts develop burrs or sharp edges due to drops;

Whether small components (such as small pendants on earrings or beads on bracelets) have a risk of detachment (to prevent children from swallowing or skin scratches).
